Asked by Julian Zimmerman on Dec 15, 2021 FAQ



For more information about Xamarin.Forms markup extensions, see XAML Markup Extensions. The Self relative binding mode is used bind a property of an element to another property on the same element:
Additionally,
Xamarin.Forms Data Binding. Data binding is the technique of linking properties of two objects so that changes in one property are automatically reflected in the other property.
Subsequently, The Self relative binding mode is used bind a property of an element to another property on the same element: In this example, the BoxView sets its WidthRequest property to a fixed size, and the HeightRequest property binds to the WidthRequest property. Therefore, both properties are equal and so a square is drawn:
Besides,
A Xamarin.Forms data binding links a pair of properties between two objects, at least one of which is usually a user-interface object. These two objects are called the target and the source:
Also Know,
The BindingContext property of the StackLayout is set to the slider object. This binding context is inherited by both the Label and the BoxView, both of which have their Rotation properties set to the Value property of the Slider: In the next article, you'll see how the binding mode can change the flow of data between target and source objects.
